Measurement of the Interantral Bone in Implant Dentistry Using Panoramic Radiography and Cone Beam Computed...

Area of Science:

• Dentistry
• Oral and Maxillofacial Surgery
• Radiology

Background:

• Dental implant placement in the fully edentulous maxilla requires adequate interantral bone.
• Accurate assessment of bone dimensions is crucial for successful implant outcomes.
• Various imaging modalities are used, but their comparative accuracy for specific anatomical regions needs clarification.

Purpose of the Study:

• To analyze the dimensions of interantral bone available for dental implant placement in the fully edentulous maxilla.
• To compare the accuracy of panoramic radiography and computed tomography (CT) in assessing interantral bone height (IBH).
• To evaluate interantral bone width (IBW) using CT.

Main Methods:

• Interantral bone height (IBH) was measured using both panoramic radiography and computed tomography (CT).
• Interantral bone width (IBW) was measured using CT.
• Statistical analysis was performed to compare measurements between imaging methods and anatomical areas.

Main Results:

• A significant difference (p < 0.001) was found in IBH assessment between panoramic radiography and CT in the canine area.
• CT scans revealed significantly higher bone in the canine area compared to incisor areas (p < 0.001).
• Significant variations in IBW were observed, with the central incisor area being widest and the lateral incisor area narrowest (p < 0.001).

Conclusions:

• Panoramic radiography is sufficiently accurate for IBH imaging in the incisor area.
• Panoramic radiography is not sufficiently accurate for IBH imaging in the canine area.
• CT provides more comprehensive and accurate measurements for both IBH and IBW in the edentulous maxilla.
